Frequently Asked Questions
What is an Expander System?
An Expander System is an advanced pivoting technology designed to prevent and repair wear in pivot joints. It replaces traditional straight pins and locks into the pivot lugs to eliminate play and movement.
How does the Expander System work?
The system consists of a pin with tapered ends, expansion sleeves, tension washers, and fasteners. When the fasteners are tightened, the sleeves are pressed up the tapered ends of the pin, expanding to conform to the wear pattern of the pivot lugs, securing the system firmly.
What are the main benefits of using an Expander?
Key benefits include permanent elimination of pivot wear, faster installation, no need for line boring or welding, increased safety, and significantly reduced maintenance costs over the lifetime of the machinery.
Can it be installed directly into worn pivot joints?
Yes, the Expander System can be installed directly into worn pivot holes without prior line boring. The expanding sleeves adapt to the wear and create a perfect, custom fit immediately upon installation.
In which industries is the Expander commonly used?
It is widely used in heavy industries such as construction, mining, forestry, agriculture, manufacturing, and oil & gas, where machinery undergoes heavy, repetitive stress on pivot joints.
Is the Expander System reusable?
Yes, the system can be dismantled and reused. If the machinery needs servicing, the Expander System can be easily uninstalled and reinstalled, saving time and money during routine maintenance.
